An uncommon species of snake documented in Chorla Ghats area.



The Chorla Ghats area of the Mhadei Bio region has yielded an addition to the number of ‘Wolf snake’ species found in this region with the documentation of an uncommon species by name of ‘Barred Wolf Snake’ (Lycodon striatus).
A slender bodied snake with a flattened head and a glossy black back inter spread with a series of white bars across its body, which diminishes towards the tail. This species has interesting faint yellow colored mid spots that resemble the shape of diamonds when observed from close and are a key to its field identification along with the characteristic white lip scales that this species possess!
The Barred wolf snake is a shy nocturnal non venomous species of wolf snake with a very mild temperament and is known to hide its head under its own coils when provoked or disturbed, thereby turning itself into a peculiar ball of coils!
Growing up to a length of 43 cms maximum this species is known to display parental care of its eggs and its clutches include anything from 2-4 eggs which are laid in July and August. It is known to feed on geckos and skinks and
Known to inhabit semi dry and fringe forest areas, the Barred Wolf snake has been reported in Goa earlier from the Mollem National Park by the then RFO Mr. Prakash Salelkar a few years ago. This specimen however was recorded from a grass patch near a human settlement in the Chorla Ghats area and was observed to be foraging in search of prey in the night.
Though known to be common in the country, there have been very few records of this species in this region. The documentation of this species in the Chorla Ghats makes the number of wolf snake species found in this region to three, which includes the Common Wolf snake, the Travancore Wolf snake and the Barred Wolf snake. The Chorla Ghats area in particular and the Mhadei Bio Region in general is being increasingly recognized by wildlife researchers as a hotspot for lesser known biodiversity and the documentation of this species has reconfirmed the need to conserve the niche habitats of this region.
Documented at a height of 400 meters above sea level by Nirmal Kulkarni, a herpetologist working in the area under the aegis of the Mhadei Bachao Abhiyaan, the ‘Barred Wolf Snake’ and many other reptilian wonders await appreciation and protection in this region that is threatened by the Mhadei Diversion Project which aims to irreversibly alter large tracts of rich Western Ghats habitats and threaten the very existence of many lesser known species in the process!

Frogs in Goa: Frequently Asked Questions

Are frog populations in Goa really on the decline?
Yes they are. Frog populations can be assumed to be declining in Goa, just as it they are in the rest of the world. Globally, frog species are disappearing at an increasingly rapid rate, faster than they have ever done in the past 65 million years.
In India, studies in 1999 and 2002 have been conducted by amphibian specialists in coordination with International agencies like the International Union for the Conservation of Nature and Natural Resources (IUCN). Moreover basic surveys and compilation of checklists on different frog species have also been carried out by researchers at the Goa University’s Department of Zoology, the Goa Forest Department in conjunction with local individual herpetologists that indicate their depleting numbers.
There is however, a serious need for long term monitoring of Goan frog populations existing in Goa.

What are the reasons for this decline?
There are a number of threats to the existence of frog species, however in Goa the chief threats are:
Poaching and consumption of frogs without allowing them to breed. At the onset of the monsoons frogs end their aestivation and come out to breed. Selective poaching of the mature bigger adult frogs before the frog can breed, will defiantly lead to a catastrophic decline, drastically reducing the number for a future frog population.
The toxic effects of use chemical fertilizers and pesticides in agriculture. Flooded paddy fields are ideal habitat for frogs. Frogs absorb water through their skin, and thus are particularly vulnerable to the toxic effects of residual chemicals that concentrate in ponds and low lying fields.
Habitat destruction. Rampant filling of fields and clearing of forest cover, besides encroachment on forests by human activities such as mining, construction, etc have possibly caused entire resident populations to dramatically decline within a short period.
Human interference in ecological balance. A significant global trend that is threatening frog populations as a whole worldwide include climate change, global warming, introduction of invasive species and the transfer of disease from farmed to wild frog populations.

Are some species more vulnerable than others?
Yes. In Goa, the two largest species; the Indian Bullfrog (Hoplobatrachus tigerinus) and the Jerdon’s Bullfrog (Hoplobatrachus crassus), are selectively poached for their large fleshy legs, the most prized anatomy of the frog. The Indian Pond Frog, Grass Frog and the Common Indian Toad are also occasionally poached.
An insatiable demand at restaurants for illegal frog meat has ensured a lucrative return to the poacher for a pair of frog legs.
Noticing the dramatic decrease in numbers of these two species; the Indian Bullfrog and the Jerdon’s Bullfrog, are now listed as threatened species that require protection against hunting or harvesting in the Schedule-I List of the Wildlife Protection Act of 1972 set up by the Government of India, as well the IUCN Red List recognized internationally.

What is the law?
The Government of India in 1985 declared a blanket ban on the catching and the killing of frogs under the Wildlife (Protection) Act 1972. This implies that any individual or restaurant detected to be catching, killing, selling, serving or even eating frog meat violates the provisions of the Act. This would attract stringent punishment with a fine of Rs 25,000 and/or imprisonment upto 3 years. In 2008, 10 persons were detained and fined under this act. Repeated offenders can get even more stringent punishment by possibly revoking their commercial licenses.

Ok, but why do I have to stop eating frog? How will it affect me?
A lot more than you realize…
Eating frog meat can jeopardize human health to the toxic chemicals absorbed by frogs from the environment. Due to the massive toxic pesticide residues that accumulate in the fat deposits of frog meat, consumption of frogs can trigger paralytic strokes, cancer, kidney failures and other deformities. Frog meat is contraband and usually processed in unsanitary conditions, with no regulation what so ever.
Frogs are the pulse of Goa’s environment, a very unsung yet crucial component of the ecosystem bridging a vital link as predator and prey in the food chain. Their impending extinction will have a ripple effect on the ecosystem, which we have not yet fully foreseen, by throwing a delicate ecological balance out of gear.
Frogs and tadpoles are voracious eaters, and consume millions of mosquitoes and mosquito larvae every year. One of the suspected reasons for the recent increase in recorded cases of malaria and other vector borne diseases in Goa, can be attributed to the decline in the numbers of frogs.
In Goan mythology frogs are believed to bring prosperity and good rainfall.

How can I help to save our frogs?
Firstly, discourage others, if not yourself from consuming frog meat. If there is no demand for frog legs, frog-poachers simply won’t catch them. Secondly, if you come across people poaching frogs or restaurants serving frog meat, report it to the police (100/108) or any of these Forest Department official’s, preferably at the location closest to you –

Green Valley Clean up








After a very interesting and informative talk on Garbage management by the Waste
Consultant, Clinton Vaz, organized at Earthworm, your neighborhood ecostore, on 21st
May at 7: 00 p.m., the actual cleanup was undertaken by a small but enthusiastic group on Sunday 24th May.

The Group comprising of residents and non residents of Green Valley met at 8: a.m., put
on their yellow cleanup gloves, picked up cartons and sacks to collect garbage in and set
off to start collection.
The areas/street outside Rochelle’s home were tackled by Rochelle, Rashmi and Rhea;
the areas around Bhobhe Residency was covered by Kenneth and young Christopher (who did a fantastic job of picking and carrying heavily laden carton of junk) and Amit; The
Vergese kids, Ethan and Amanda (despite their late arrival the night before from their
holiday, jumped in to help) along with Devdatta and Madhura took on the far end of
Green Valley.
Roopa cleaned up around Earthworm area and Nirmal helped some and then
photographed, delegated and strolled everywhere surveying the area and preparing the
next plan of action! Ahmed the garbage contractor of Panaji municipality and his helper
came from Panaji to go into the deeper parts to collect garbage, segregated it and
packed off the garbage collected.

We found
Loads of plastic…unlike popular notion that ‘someone from outside dumps the stuff’ we realized that most of the garbage came from the residents itself.
Thermacole, plastic bags, plastic bottles were found and surprisingly each group found loads of dumped broken/unbroken glass bottles.
Loads of Garbage was seen dumped at the corners of roads.. under the bridge was littered so heavily and so deep that it would take a whole 2 weekends to make it look even a bit more presentable.
MOSTLY, We all realized that the TWO HOURS WERE NOT SUFFICIENT to clean up Green Valley. We decided that a task well started should not be left half done!
So……We would like to continue our clean up for the next 3 consecutive Sundays too. And then on a monthly basis. The Timings remain the same 8:00 a.m. to 10 a.m. Please do join in … More hands make clean work.

Please do not forget to thank Kenneth, Rochelle, the Vergese kids and Christopher for giving you a cleaner surrounding!! Thanks to Rhea, Devdatta, Madhura, Amit, and Rashmi who do not live in Green Valley but have helped clean it up for us.

How you can contribute to Keeping Your Valley Clean

Do not litter around your residential area (in particular) and Green Valley(in general) and please do not be passive if you see anybody else littering and request them to pick up their garbage.

Pick up any garbage you see lying around whist going for walks. Don’t wait for someone else to do it. Worst still, do not tolerate or get used to seeing it around you. ( you can come and pick up a set of gloves from earthworm for this exercise)

Separate your wet (biodegradable) waste from your dry waste (non biodegradable) that is paper, plastic, thermacole, tetra pack, glass. All these can be separated AT SOURCE that is in your home right at the time of discarding itself. The good news is even the smallest bit of plastic, paper etc. can be sent for recycling if put away neatly.

Do not burn your waste (biodegradable or non biodegradable) especially plastics as they release toxins which we all inhale.

Compost your biodegradable waste. There are many ways of doing this. You can visit Earthworm for solutions/suggestions for composting.

Sensitize your hired help not to throw your household garbage in the valley. Tell them about the Green Valley Residents Cleanup.

To know how to send your dry waste for recycling please call earthworm, we can give you telephone numbers of waste collectors to come and collect your separated dry garbage from your home on a weekly/monthly basis.

Join us in our clean up whenever you can. It keeps the spirits up and keeps all of us motivated, especially the kids who have jumped to the cause.

Please contact us at Earthworm 9766358343/ 2410871 to find ways to contribute to Keeping Green Valley clean.

The Russell’s Viper-a awe inspiring species

It is 11.30 in the night and I am standing against a mud wall of a small warm home in the village of Aldona. With a headlight on my forehead and a thumping heartbeat, I tune in to the environs. I must admit that it is very eerie to hear a pressure cooker whistle like sound at this hour, especially from under a wooden bed where stacks of Rice bags and large aluminum utensils seem to share space with one of the most commonly feared and revered of Indian reptiles that has crawled our world. I stoop down to and focus my headlight in the direction of the sound to reveal a breathtaking coiled wonder, one that sends a shiver of excitement down my spine- as here I am face to face with the Russell’s Viper (Daboia russellii), and a huge specimen at that.
Locally known as Kusdo or Ghonas, this large thick set ground dwelling viper is crepuscular in nature-i.e. active at dawn and dusk and is found near human habitation very often due to its fondness for rodents and their like. Besides which it has been known to feed on birds, lizards, frogs and even crabs on some occasions. A sluggish slow snake, capable of a fast strike when disturbed or threatened, the coloration of a Russell’s Viper varies from deep brown to brownish yellow with a set of three dark brown rows of spots that are lined with white edges and meet to form what is commonly known as ‘chain markings’, a sign that helps laypersons stay away from this snake when encountered in the neighborhood! The head is a triangular and broader than the neck, a sign of this species belonging to the Viper family while the tail is short and abrupt! While the skin is rough and the scales are strongly keeled, it is still in demand as the color patterns on the skin make it a target for skin dealers to be used for illegally manufacturing purses and shoes, a practice that has now ceased thanks to the inclusion of this species as a Scheduled species. But despite this, at a local level, Russell’s vipers are often killed as they are feared to cause death instantly according to the locals.
The individual I rescued from under the bed at Aldona measured a little less than a meter, and was definitely a female ( scalation proved that), and while the largest record for Goa is a 1.5 meter female, male Russell’s Vipers grow up to a meter in length.
Russell’s vipers are also unique in nature as they are viviparous which means they give birth to live young ones numbers ranging from anything between 8 to 60 individuals during the months of March- July.
Capable of fast strikes as mentioned earlier, the Russell’s vipers prefer to forewarn intruders and predators with their loud hissing and strike only as a last resort. The venom is a mixture of haemotoxic as well as neurotoxic venom and affects the blood vessels and to an extent the central nervous system, causing muscle pain and stiffness coupled with bleeding from the area of the bite. And while these are symptoms that appear for a Russell’s viper bite, the fact remains that the bite is cent percent curable with the administration of Anti venom serum provided it is treated with utmost urgency. Considered to be part of the Big 4- i.e. the 4 venomous common snakes of India, the Russell’s viper venom is also used in medical research today.
It is here that I would also like to mention that one of the beacons of Indian Snake venom and allied research, Dr. R C. Kankonkar passed away recently and was cremated at Sada in Vasco. His work on the venom and its local necrotizing of the Russell’s viper and the efficacy of the Haffkine Institute Poly venom on Indian snakes is considered as a path breaking scientific work for the country as far as modern day toxicology is concerned. I offer my silent prayers to this great scientist and guide for our generation and hope to receive his blessings through his pioneering work for the reptiles of our land as well as the human population that lives in harmony with them.
I leave the small Aldona home by expressing my gratitude to its residents for not having killed the snake and hope that this species will continue to help us keep the rodent population in check thereby rendering a yeoman service to the urban ecosystem at large.

Amphibians in decline- the national and state scenario.

The Save our Frogs Campaign in Goa is gathering momentum with support from all quarters and while nature lovers ecologists and concerned citizens are joining hands with the Goa Forest Department to create awareness and conserve Indian Bull frogs in particular and all other frog species in general.
It is however important to look at the national scenario too so that we realize the seriousness of the issues at hand concerning Amphibian diversity and about the declining amphibian populations that are now in dire straits.
According to the IUCN Red List of Threatened species, at least 1,856 amphibian species are threatened with extinction, representing 32 percent of all known species worldwide

Scientists fear that more than 50 amphibian species worldwide have already become extinct over the last 15 years alone, which includes over 18 species from South Asia
alone. This high rate of decline of amphibian species across the world provides an indicator for the health of natural ecosystems in all regions and is a cause of concern.

Currently there are approx 427 species that are considered Critically Endangered (CR), 761 are Endangered (EN), and 668 species are Vulnerable (VU) worldwide. In India an Assessment of Amphibians under the Conservation Assessment and Management Plan (CAMP) workshop conducted by Biodiversity Conservation Prioritization Project, India has listed 32 species as Critically Endangered, 71 species as Endangered, 52 species as Vulnerable and 9 species as Near Threatened species. Over 63 species were listed as Data deficient as no research data was available on them.

While 63 percent of Indian amphibians are endemic to India, i.e. found only in the country 37 percent are considered non-endemics and are found across the world besides the country. The Western Ghats is considered as one of the richest areas of endemism as far as amphibian diversity is concerned followed by North East India and Sri Lanka. Goa’s forests are part of the Western Ghats landscape and the need of the hour is to conserve and protect these forests for amphibian conservation.

Threats for amphibian species in India include habitat destruction, fragmentation, and agricultural practices like shifting cultivation, pollution, pesticides and human consumption for meat. The laws that protect amphibian populations include the Wildlife Protection Act, the Biodiversity Act and the Prevention of Cruelty to Animals Act besides others.

The Jerdon’s Bullfrog, poached for its meat in Goa is listed as Near Threatened while the Indian Bull frog, another victim of large-scale hunting is listed as Vulnerable. The Malabar Gliding Frog, an endemic species of South Asia found in Mhadei Wildlife Sanctuary and the Mollem National Park is listed as a Near Threatened species. Amongst other species found in Goa the Beddome’s Leaping frog is listed as Vulnerable while the Jerdon’s Narrow mouthed frog is listed as Near Threatened on a global scale.

The need to intensify policing as well as create awareness amongst the masses of the state as well as national scenario with regards to declining amphibian populations is the need of the hour. It is now a known fact that these lesser known life forms play an important role in every ecosystem and are key indicators of monsoonal patterns, climate change and habitat quality besides a host of other dynamics that influence our environment. It is important that we thus aware that our survival depends on their survival and this is the only way forward.
